I use a StarSense unit on my CGEM mount to do a manual plus a polar align.
So I would start with the index markings, point to 5 positions in the sky and have them captured. I would then add two more alignment positions.
Then I do a polar align and move my mount with the knobs as required.
The HC then shows a message that one should align once again but I am not sure what is the best way to first reset / delete the previous alignment data.
Up to now I have just switched the mount off an on again but that is not ideal. Any suggestions how to clear out the memory completely and start fresh?
